Using a network of over 500,000 zombie computers known as the Mega-D botnet, Nikolaenko churned out 10 billion spam emails a day at the height of his operation. These advertised mostly counterfeit goods and herbal remedies--one Rolodex counterfeiter who was his client said he spent $2 million on spam advertising. But starting in 2007, the FBI began closing in on Nikolaenko. He was arrested on Nov. 4th, while in Las Vegas for a car show, and now faces a $250,000 fine and up to three years in prison."
